Von Vorteil ist dabei, dass eine Verliersicherung gebildet ist, insbesondere sowohl in axialer Richtung als auch in Umfangsrichtung. Dabei ist die Erfindung einfach realisierbar und benötigt keine weiteren besonderen Mittel mit Ausnahme des Zylinderbolzens, also eines kreisscheibenartigen Teils. An der Adapterwelle ist ebenso wie an dem Spannring eine Vertiefung vorzusehen, so dass der Zylinderbolzen in beiden Vertiefungen aufnehmbar ist. Infolge der Axialschlitze ist die Adapterwelle elastisch auslenkbar und somit andrückbar an die Hohlwelle, sobald der Gewindestift auf die Adapterwelle drückt. Dabei wird das Sich- Zusammenziehen, insbesondere das Aufschrumpfen, bewirkt. Für den Gewindestift ist eine durch den Spannring durchgängige Gewindebohrung vorhanden.

In the adapter shaft 1, a solid shaft, not shown in the figures is introduced. Thus, this solid shaft is surrounded by the adapter shaft 1 radially. A threaded pin 2 is screwed into a through the clamping ring 4 radially continuous threaded hole and presses on a arranged on the adapter shaft 1 flattening 20th
Die Abflachung 20 ist an der Außenseite der Adapterwelle 1 ausgeführt und tangential zur Mittelachse oder Drehachse der Adapterwelle ausgerichtet. Im von der Abflachung 20 überdeckten axialen Bereich ist die Adapterwelle 1 an ihrem äußeren Umfang zylindrisch ausgeführt mit Ausnahme der Axialschlitze und einer weiteren Vertiefung mit Bodenfläche 30. The flattening 20 is executed on the outside of the adapter shaft 1 and aligned tangentially to the central axis or axis of rotation of the adapter shaft. In the axial region covered by the flattening 20, the adapter shaft 1 is cylindrical at its outer circumference, with the exception of the axial slots and a further depression with a bottom surface 30.
Der Gewindestift 2 drückt auf die Abflachung 20. The threaded pin 2 presses on the flattening 20.
Somit ist mittels Einschrauben des Gewindestiftes 2 in die durch den Spannring durchgehende Gewindebohrung ein Andrücken der Adapterwelle 1 an die Vollwelle ermöglicht. Thus, by screwing the threaded pin 2 in the continuous through the clamping ring threaded hole pressing the adapter shaft 1 allows the full wave.
Vorzugsweise ist die insbesondere radial gerichtete Vertiefung mit Bodenfläche 30 diametral gegenüber von der Abflachung 20 angeordnet und dient als Andrückfläche für einen Preferably, the particular radially directed recess with bottom surface 30 is arranged diametrically opposite the flat 20 and serves as a pressure surface for a
Zylinderbolzen 3, welcher in einer insbesondere radial gerichteten Vertiefung am Innenumfang des Spannrings 4 ausgebildet ist. Dabei greift der Zylinderbolzen 3 ein in die Vertiefung und ist mittels einer anderen Ausnehmung im Spannring gehalten. Cylinder pin 3, which is formed in a particular radially directed recess on the inner circumference of the clamping ring 4. In this case, the cylinder pin 3 engages in the recess and is held by means of another recess in the clamping ring.
Dadurch ist eine Verliersicherung in axialer Richtung und in Umfangsrichtung bewirkt. This causes a captive securing in the axial direction and in the circumferential direction.
Wie in Figur 5 gezeigt, wird der Zylinderbolzen 3 zunächst in die insbesondere radial gerichtete Vertiefung am Innenumfang des Spannrings 4 eingelegt und dann der Spannring 4 auf die Adapterwelle 1 aufgeschoben. Dabei bewirkt eine Fase 41 , die als Einführschräge wirkt, ein leichtgängiges Aufschieben der Adapterwelle 1 auf den im Spannring 4 As shown in Figure 5, the cylinder pin 3 is first inserted into the particular radially directed recess on the inner circumference of the clamping ring 4 and then the clamping ring 4 is pushed onto the adapter shaft 1. In this case causes a chamfer 41, which acts as an insertion, a smooth sliding the adapter shaft 1 on the in the clamping ring. 4
aufgenommenen Zylinderbolzen 3. Bei diesem Aufschieben wird die Adapterwelle 1 elastisch verformt, insbesondere radial gedrückt. Infolge der Axialschlitze ist diese elastische taken cylinder pin 3. In this sliding the adapter shaft 1 is elastically deformed, in particular pressed radially. Due to the axial slots, this is elastic
Verformung mit geringem Kraftaufwand bewirkbar. Deformation with little effort feasible.
Sobald der Zylinderbolzen 3 die Vertiefung mit Bodenfläche 30 erreicht, wird er durch die von der elastischen Auslenkung erzeugt Gegenkraft in die Vertiefung gegen die Bodenfläche 30 gedrückt. Somit ragt dann ein Bereich des Zylinderbolzens 3 in die Vertiefung mit Bodenfläche 30 der Adapterwelle 1 hinein und ein anderer Bereich in die Vertiefung an der Innenwandung des Spannrings 4. As soon as the cylinder pin 3 reaches the recess with bottom surface 30, it is pressed by the counterforce generated by the elastic deflection into the recess against the bottom surface 30. Thus, an area of the cylinder bolt 3 projects into the recess with bottom surface 30 of the adapter shaft 1 and another area into the recess on the inner wall of the clamping ring 4.
Die Fase 41 ist zwar im axialen Endbereich der Adapterwelle 1 angeordnet, also zwischen dem axialen Ende und der Vertiefung mit Bodenfläche 30. Die Fase 41 erstreckt sich in Umfangsrichtung nur teilweise, insbesondere überdeckt sie weniger als 180° in Umfangsrichtung. In dem restlichen, also nicht von der Fase 41 überdeckten Bereich in Umfangsrichtung ist ein radial hervorragender Wulst 40 ausgebildet, welcher sich aber nicht über den gesamten restlichen Umfangswinkelbereich erstrecken muss sondern vorzugsweise nur über denjenigen Umfangswinkelbereich, welcher von der Abflachung 20 in Although the chamfer 41 is arranged in the axial end region of the adapter shaft 1, ie between the axial end and the recess with bottom surface 30. The chamfer 41 extends in Circumferential direction only partially, in particular, it covers less than 180 ° in the circumferential direction. In the remaining, so not covered by the chamfer 41 area in the circumferential direction, a radially outstanding bead 40 is formed, but which does not have to extend over the entire remaining circumferential angle range but preferably only over that circumferential angle range, which of the flattening 20 in
Umfangsrichtung überdeckt wird. Circumferential direction is covered.
Vorzugsweise ist der Wulst 40 dadurch gebildet, dass die Abflachung 20 in einen zylindrischen Bereich eingearbeitet wird und somit am Rand der Wulst 40 entsteht. The bead 40 is preferably formed in that the flattening 20 is worked into a cylindrical area and thus arises at the edge of the bead 40.
Der vom Wulst 40 axial überdeckte Bereich überlappt also mit dem von der The area axially overlapped by the bead 40 thus overlaps with that of the
Fase 41 axial überdeckten Bereich oder umfasst ihm. Dabei ist also der von Fase 41 überdeckte Radialabstandsberiech kleiner als der vom Wulst 40 überdeckte Chamfer 41 axially covered area or includes him. In this case, the Radialabstandsberiech covered by chamfer 41 is smaller than that of the bead 40 covered
Radialabstandsbereich oder schließt sich an ihn radial an, insbesondere ist er also radial innerhalb angeordnet. Radial distance range or joins him radially, in particular it is therefore arranged radially inside.
Die jeweilige Vertiefung umgibt somit den Zylinderbolzen 3 und fungiert somit als The respective recess thus surrounds the cylinder pin 3 and thus acts as
Verliersicherung. Die Vertiefung mit Bodenfläche 30 ist vorzugsweise als Ansenkung in der Adapterwelle 1 ausgeführt. Captive. The recess with bottom surface 30 is preferably designed as a countersink in the adapter shaft 1.
Die Adapterwelle 1 , der Gewindestift 2 und der Zylinderbolzen 3 sowie der Spannring 4 bilden somit ein System zur kraftschlüssigen Verbindung aus. The adapter shaft 1, the threaded pin 2 and the cylinder pin 3 and the clamping ring 4 thus form a system for non-positive connection.
Im oberen Teil der Figur 1 ist sichtbar, dass der Spannring 4 auf dem Wulst 40 aufsitzt und im unteren, also diametral gegenüberliegenden Teil der Figur 1 ist die als Einführschräge 40 ausgebildete Fase 41 sichtbar, die vom Spannring 4 beabstandet ist. Denn der Wulst 40 ist radial weiter ausgedehnt als die Fase 41. Die Innenwandung des Spannrings 4 ist hingegen wie in Bereich eines Rotationskörpers ausgeführt, also mit in jeder axialen Position In the upper part of Figure 1 it is visible that the clamping ring 4 is seated on the bead 40 and in the lower, that is diametrically opposite part of Figure 1, the chamfer 40 formed as a chamfer 41 is visible, which is spaced from the clamping ring 4. Because the bead 40 is radially extended further than the chamfer 41. The inner wall of the clamping ring 4, however, is designed as in the region of a rotating body, so with in any axial position
konstantem Radialabstand, also von der Umfangsposition unabhängigen Radialabstand. Die Erfindung ermöglicht also eine Spannverbindung, insbesondere constant radial distance, so independent of the circumferential position radial distance. The invention thus enables a clamping connection, in particular
Schrumpfscheibenverbindung, zwischen einer Adapterwelle und einer Welle, insbesondere Vollwelle. Der Wulst 40 ermöglicht also auch in axialer Richtung eine zusätzlich formschlüssige Begrenzung des Gewindestiftes 2. Shrink disk connection, between an adapter shaft and a shaft, in particular solid shaft. The bead 40 thus also allows in the axial direction an additional positive boundary of the threaded pin. 2
